I started a thread last week about customizing the behavior of
ControlDecorationSupport ("[databinding] ControlDecorationSupport idea").
The idea was that a red "X" would only show up if the user had modified a
field.
I would like to do the same for WizardPageSupport/DialogPageSupport.
Currently, these classes have the intelligence to hide page error messages
initially. But as soon as any field changes, the page errors are shown even
for untouched fields. For example:
___________________ ___________________
Enter your name. X Last Name is required
___________________ ___________________
--->
First Name: *______ First Name: _Will___
Last Name: *______ Last Name: *______
I would like the asterisk to speak for itself until the user has actually
interacted with the field. My workaround (as with ControlDecorationSupport)
is to use a custom status which is aware of whether it is the initial
validation. But unlike ControlDecorationSupport, I see no clear way to
provide custom handling for it in DialogPageSupport. The best I have come
up with required me to subclass DialogPageSupport and copy/paste
handleUIChanged, handleStatusChanged() and handleStatusException(). The
first two methods have a @noreference and the third is private so this is
clearly not desirable.
Any ideas?
